This document discusses a "smart farm" project that uses sensors, internet connectivity, and semantic technologies to monitor and manage a farm. The project collects data from 100 soil sensors and 2 weather stations on the farm. It uses an ontology and linked open data to semantically integrate and provide open access to the sensor data. Machine learning algorithms could potentially generate predictive models from the sensor data to estimate values without physical sensors. The system detects events on the farm like cattle leaving and alerts farmers. It aims to help farmers make informed decisions and remotely monitor their farm operations.

IN COLLABORATION WITH
2. Smart Farm
• Informed Farming
• Precision agriculture
– Sensors, information system, decision support systems
– System exists within a farm-gate
• Connected Farm
• Devices in the farm are connected with each other and the world using
internet
• Farmers are connected to the farm devices, other farmers and experts
• Things (e.g. Cattle) in the farm can be monitored remotely.
• Integrated Farm
• Includes Farmers in the supply chain - suppliers, logistics, consumers – back
to the farmers to complete the loop.

5. What do farmers want?
• Measurement data produced by 100 sensor every couple of
minutes?
• Weather measurement produced every couple of minutes?
• Cattle location updated frequently?
• Farmers are interested in the alerts about the things in the farm.
•
•
•
•
Cattle leave the farm
When to sow
Current market value of their livestock
Soil in a paddock is compacted
• Researchers/Experts are interested in the data.

9. GSN Extended
• Geo-Spatial Analysis
• Implemented using R and Java packages
• Event (Alert) Processing
• Extended GSN to process event descriptions and produce alerts
• Synchronous and Asynchronous events
• Farms can create their own events
• Semantic Web Enablement
• Sensor data stored in MySQL
• Linked data are produced using defined URIs
• Statistical data are stored in Virtuoso triple store
– Provides open access to everyone, analyse data using SPARQL
– VisualBox and Google APIs for visualisation

16. Machine Learning Opportunities
• Cost of Sensor Networks
• Variations are possibly correlated and predictable
• Soil variation, elevation -> soil ec, temp, vwc
• BOM forecast -> farm weather
• Data collected over last 2 years
• Use to generate predictive model
• Produce sensor data without sensors.
Because data from Sensor networks in farms worth
more than the sensor networks!
